Another thing I liked was that they give you a timer that calculates how much time you have left, which is a really nice feature that will take away the stress of worrying about your credit balance.
And you can always tip the performer should you feel she deserves it.
And they offer one of my favorite features, which is being able to hover over a thumbnail and get a look inside the performer's live room.
The number of performers on Flirt4Free varies depending on when you log in.
The site is also mobile-friendly and I browsed on an Android phone and everything worked just fine.
